wireless lan problem

Wlan falling out:

When I play a video file from a NAS server (stardom SL3620-2s-lb2) on my portable with (intel pro/wireless 3945abg network adapter) I drops out every 3 minutes.

First I thought I was the NAS server, but if I play three different files with three different players it has no problem playing all three files.

So the actual problem is that if I play in one player (any player, all tested (vlc,mpc,wmp)) it drops out.

If I copy a file from the NAS server I goes to at least 25% of the actual bandwidth, if I run three video files I goes between 6-9%, so I is around 0.5-3% when I play one file and then it drops out.

So it is not, the speed of the NAS or the Wlan (fritz-box 7260), I have tried to turn of the firewall, I can play mp3s without any dropout, so I should not be disturbance on the signal from the wlan box.

Is there any setup in the Fritz-box 7270 there can be turned of, since I think that it must be there the error could be.

By the way I have the last drivers for the Network adapter.

Many regards

Rai Come

When you quote something, such as the name of device or a model, please make sure it's accurate before you submit your post.

- you don't have a Fritz-box, you have a Fritz!Box.
- it's a combo DSL/ADSL high speed modem/router, with additional features.

Do you have the 7260 or the 7270 model?

"intel pro/wireless 3945abg network adapter"

It appears that's probably built into your laptop or whatever you have.

IntelĀ® PRO/Wireless 3945ABG Network Connection

Apparently it's rated 54mbps max.

Firewall problems do not cause dropped wireless connections - either the firewall allows something through the router or it doesn't. Firewall settings may affect the max. throughput for accessing certain sites via certain software ports, but if it does, that has no relation to dropped wireless connections.
If you don't have a problem when you connect to the Fritz!Box via a network cable, your problem is not caused by any firewall setting.

Crappy wireless connections, or a lot less likely a problem with your high speed modem connection, (see below - Universal DSL/ADSL stuff) causes dropped wireless connections.

If your icon for the strength of the wireless connection with the four vertical green bars on it has three or fewer bars green, your wireless connection has a problem and the connection will not be reliable.

Lots of people have problems with wireless A/B/G dropping connections. If you can connect via wireless N (A/B/G/N) you probably won't have a problem with dropped wireless connections.

If you have the Fritz!Box 7270, it's wireless A/B/G/N.
If you buy yourself a wireless N adapter, USB, or better (doesn't use up a USB port) a PCMCIA or ExpressCard adapter, and use that instead of the built in wireless adapter, it's very likely you won't have the problem with dropped wireless connections.

If you have the 7260, I'm assuming it's wireless A/B/G, or B/G.
In that case, using a wireless USB, PCMCIA, or ExpressCard A/B/G or B/G adapter instead of the one built into the laptop may cure your problem.

Whatever your model, if you connect to the Fritz!Box with a network cable instead of the wireless adapter, you will very likely not have any problem with dropped connections.

Universal DSL/ADSL stuff.

These things affect the reliabilty and speed of internet connections of the high speed modem component of your Fritz!Box for both wireless and wired connections connected to your Fritz!Box.
If you don't have a problem when you connect to the Fritz!Box via a network cable to your computer, you probably don't have a significant problem with these things.

Telephone line noise.

The cheap flat phone cable between the Fritz!Box and the telephone wall outlet acts like an antenna - it picks up electric and electronic noise from it's environment.
- the noise the telephone cable picks up is directly proportional to the square of the distance from the source - e.g. twice the distance, 1/4 the strength. Have the cord located as far away as you can from possible sources of noise - e.g. unshielded speakers, flourescent lights, AC power cords, motors, fans, etc. etc.
- The shorter the cord is the better.
If it's a lot longer than 6 feet/2m or so, you can have problems with your DSL/ADSL connection you don't have when it's shorter. In that case, if you do have connection reliability problems, you need to use twisted pair telephone cable (the type commonly used within your walls to the wall jacks) to the the connection in the nearest wall box, a connection box with a jack the cord can be plugged into, and a shorter cord with the plugs on both ends between the Fritz!Box and that connection box.
- the noise can be picked by any such phone cord connected to the same phone line that's connected to the Fritz!Box, so it isn't necessarily just the one plugged into the Fritz!Box that is picking up the line noise.

As well as it being possible noise is being picked up by the the telephone cable plugged into the Fritz!Box, or other such cables at your location, if there is electric or electronic noise being picked between your location and the nearest telephone exchange, you will have DSL/ADSL connection problems. At the very least that reduces the max DSL/ADSL speed on the web some - if it's worse, it can cause the connection to be very poor and slow or even disconnect, and you need to re-boot the Fritz!Box to establish a better connection (switch it off/on, or remove it's power adapter plug, plug it back in). If you pick up a phone on the same phone line as the DSL/ADSL connection for the Fritz!Box, and you hear static or clicks or pops or a hum or another noise, you have that proplem, but on the other hand, the noise can be inaudible to humans and still be there.

You many not have the problem all the time - it may come and go.

If you suspect you have a line noise problem that is not within your location, and it seems to be always there or frequently there, try contacting your phone company to see if they can do anything about the problem (that applies even if your DSL/ADSL ISP is not the phone company - whoever owns the phone lines is who you need to contact).

Distance limit.

DSL/ADSL connected telephone lines must be no longer than a certain distance between your location and the nearest telephone exchange. If your location is nearer that limit, you're a lot more likely to have internet connection problems - lower maximum speeds on the internet, poor, slow connections intermittantly, and possibly dropped connection problems.
